On algebraic and geometric Kekulé structures in benzenoid rotagraphs

Abstract

Recently introduced algebraic Kekulé structures (AKS) describe the ▫$\pi$▫-electron distribution within rings of a conjugated network. The ratio of the AKS countto the classical Kekulé structures count was studied in benzenoid rotagraphs. By considering three representative classes of such rotagraphs, it was shown that this ratio tends towards either 1 or 0, or its value lies between 0 and 1.

Secondary title:	O algebarskim i geometrijskim Kekuleovim strukturama u benzenoidnim rotagrafovima
Secondary abstract:	Nedavno uvedene algebarske Kekuléove strukture opisuju raspodjelu ▫$\pi$▫-elektrona unutar prstenova konjugirane mreže. Omjer njihovog broja i broja klasičnih Kekuléovih struktura za benzenoidne rotagrafove proučavan je u ovom radu. Razmatranjem triju reprezentativnih klasa ovih rotagrafova pokazano je da promatrani omjer teži prema 0 ili 1, ili pak da njeova vrijednost leži između 0 i 1
